(Beraisa): Six of them [Talmidei Beis Shamai] ascended, and the rest of them stood against [Talmidei Beis Hillel] with swords and spears. (CHASAM SOFER (Bavli 17a) - the six persuaded some of Talmidei Beis Hillel to agree to some of their decrees. Other Talmidei Beis Hillel wanted to leave, to invalidate a vote. Talmidei Beis Shamai stood with swords and spears to ensure that they not leave].

(Beraisa): They decreed 18 matters [unanimously], in 18 matters [Beis Shamai] were the majority [with those of Beis Hillel who agreed], and they argued about 18 matters. (Most of the arguments are brought in the coming Mishnayos.)

They decreed [unanimously] about the following - [they forbade] bread of Nochrim, their cheese, their oil, their daughters, their semen [is Tamei], their urine [is Tamei], the laws of a Ba'al Keri, the laws of Chutz la'Aretz. (These are eight. The other 10 are in the coming Mishnah cited.)

(Mishnah): The following disqualify Terumah - one who ate a Rishon [l'Tum'ah, i.e. it became Tamei through an Av ha'Tum'ah], one who ate a Sheni (food that touched a Rishon), one who drank Tamei liquids, one whose Rosho v'Rubo (head and majority of his body) entered Mayim She'uvim (it was in a Kli), a Tahor person that three Lugim of Mayim She'uvim fell on Rosho v'Rubo, a Sefer, [Stam] hands, a Tevul Yom, and food and drink that became Tamei through liquids.

(Rabanan of Kisarin): These (what you call the first eight unanimous decrees) were among those in which [Beis Shamai] were the majority. [We count semen and urine as one, so] they are seven, and these are the [11] others:

If one was on the road when it gets dark (at the start of Shabbos), he may give his wallet to a Nochri [before Shabbos, to take it home for him].

(Mishnah): Similarly, a Zav may not eat with a Zavah lest they come to have relations.

All Metaltelim [that tower over Tum'as Mes] bring Tum'ah if they are as thick as a [standard] plowshare.

How we harvest a Beis ha'Peras [and the grapes are Tehorim].

One who leaves Kelim under an [attached] pipe [from which water flows to a Mikveh. The water is considered She'uvim, and disqualifies the Mikveh if it did not already have 40 Sa'im.]

There are six Sefekos, due to which we burn Terumah. (They count as six decrees.)

(R. Yosi bei R. Bun): Also [was decreed that day] what grows from [seeds of] Terumah [it is forbidden like Terumah. He holds that they did not agree about Kelim under a pipe.]

[Rabanan of Kisarin]: These are the [unanimous] decrees - 10 of the first [ones listed, i.e. the Mishnah of matters that disqualify Terumah]. The remaining [eight] are among [the 18] that R. Shimon ben Yochai taught;

Note: Rabanan of Kisarin hold that bread was not unanimous, and in many cases they count like one what R. Shimon counts as multiple decrees. We number the decrees according to Rabanan of Kisarin.

[R. Shimon]: That day they decreed about their (Nochrim's) bread, and (1) their cheese, (2) their wine, their vinegar, their brine and their fish oil, (3) their pickled, cooked and salted foods, (4) wheat [kernels] broken into two pieces, into three pieces, or into four pieces, (5) [preciseness of] their language and testimony, (6) their gifts, (7) [seclusion with] their sons or daughters, and (8) their Bikurim (if one sold land to them, he must buy the first fruits from it and bring them to Yerushalayim).

(R. Yakov bar Acha citing R. Yonason): Their bread was a Halachah of Im'um (unclear).

Question (R. Yosah, to R. Yakov bar Acha): What is a Halachah of Im'um?

Do we say that where bread of Yisrael is found, bread of Nochrim should be forbidden, and they questioned this and permitted it?

Or, where bread of Yisrael is not found, bread of Nochrim should be permitted, and they questioned this and forbade it?

Answer (R. Mana): Is there a Halachah of Im'um to forbid?! (Surely, it means that they permitted it!)

Question: Is bread not a Tavshil (cooked food) of Nochrim? Do we say that where Tavshilim of Yisrael are found, Tavshilim of Nochrim should be forbidden, and they questioned this and permitted them?!

Answer: Rather, where bread of Yisrael is not found, bread of Nochrim should be forbidden, and they questioned this and permitted it, for it is a life necessity.

(Rabanan of Kisarin citing R. Yakov bar Acha): [The Halachah follows] the one who permits [where bread of Yisrael is not found], but only from a professional baker.

Observation: People do not do so. (Rather, they buy even from Nochrim who are not professional bakers.)
